Selective Mutism: Practical Strategies for Teachers and Parents
Selective mutism, sometimes called situational mutism, is an anxiety-related condition in which a child is unable to speak in certain situations, despite being able to speak comfortably in others. It is best understood as a communication difficulty driven by anxiety in specific contexts, rather than a choice or a refusal to speak.
It is not the same as shyness
In school settings, selective mutism is often mistaken for shyness. A shy child is usually slow to warm up, but will gradually become more comfortable and begin to speak. A child with selective mutism shows a more consistent and predictable pattern: they find it impossible to speak to the same people, or in the same places, even though they speak freely elsewhere.
Understanding the freeze response
It is important for teachers and parents to understand that the lack of speech is not intentional. In anxiety-provoking situations, the child’s nervous system may move into a freeze response, making spoken communication extremely difficult or temporarily inaccessible. This is not stubbornness or non-compliance, but an automatic stress response, and children usually find it distressing.
How common is selective mutism?
Current estimates suggest selective mutism affects around one in 150 children in the UK. The figure falls in adolescence, to roughly one in 1,000, and again in young adulthood, to around one in 2,400. The number of older adults affected is not known, as the condition often goes unidentified.
It usually begins in early childhood, and typically becomes noticeable when children start nursery or school and are expected to communicate in new social environments. Teachers and school staff are often among the first to recognise the pattern.
Broadly, the pattern to look for is a child who:
- Does not speak in specific situations, such as school or public places
- Speaks comfortably in situations where they feel safe, usually at home
- Has shown this pattern consistently for at least a month, beyond the first weeks of settling in
Without appropriate support, a child may experience increasing anxiety around communication in school, which can affect attendance and learning. With early understanding and supportive approaches, children can make significant progress in feeling safe enough to communicate in more settings.
Practical strategies for the classroom
Supporting a child with selective mutism focuses on reducing anxiety, building safety, and gently expanding communication, without pressure.
- Remove pressure to speak:
Avoid directly pressuring, forcing, or repeatedly prompting speech. This includes avoiding rewards or consequences linked specifically to speaking. Pressure can increase anxiety and reduce the child’s sense of safety in communication. - Value all communication:
Recognise and affirm all forms of communication, including pointing, nodding, gestures, writing, AAC, or play-based interaction. These are meaningful communication attempts and should be treated as valid participation. - Create low-demand, positive interactions:
Focus on shared activities that do not require speech. Play-based or parallel activities can help the child feel safe and included while reducing communication pressure. - Follow the child’s lead:
Allow the child to initiate communication in their own time and in ways that feel manageable. If the child begins to use their voice, respond calmly and naturally to what they say, rather than placing emphasis on the act of speaking itself. - Work collaboratively and seek support:
If concerns arise, collaborate with families and the wider school team. Referral to a Speech and Language Therapist or other relevant professionals can support a joined-up approach.
“My child is not speaking in school. What can I do?”
If you are a parent rather than a teacher, the principles are the same, and there is a great deal you can do at home to take the pressure off.
- Praise your child for joining in, even when it is not with words.
Acknowledge every interaction: passing a toy, nodding or shaking their head, pointing. All of it is communication. - Concentrate on having fun together.
Enjoying interactions with other people reduces the anxiety attached to talking to them, and reduces the pressure your child feels to perform. - Follow your child’s lead when they are ready to speak.
Reassure them that they will be able to speak when they are ready. Never punish a child for not speaking. - Do not beg or bribe your child to speak.
Try not to let your child see that you are anxious about it. Your calm is part of their safety. - Share your concerns with school staff.
If school shares them, ask about a referral to their allocated therapist, or arrange a private assessment.
Getting support
When it is recognised early and handled well, most children make real progress with selective mutism. If you recognise the pattern described above, please do not accept reassurance that your child will simply grow out of it.
Speak to your GP, who can refer you to your local NHS service, or contact us to be seen privately. Email enquiries@londonspeechtherapy.co.uk or call 020 3475 2189.
